EVolve Battery Systems manufactures lithium-ion battery packs for ground robotics, autonomous ground vehicles (AGVs), mobile manipulation platforms, legged robots, and unmanned ground vehicles (UGVs). Robotics battery requirements differ from stationary or aerospace applications in one critical way: the combination of compact physical envelope, wide voltage range, burst current demand, and communication integration must all be satisfied simultaneously. EVolve NMC chemistry delivers higher gravimetric energy density than LFP, which matters when every kilogram of battery mass reduces payload or endurance. Voltage configurations from 24V to 200V. CAN bus BMS interface is standard. All systems manufactured in Boulder, Colorado, USA.
Battery packs for factory-floor autonomous mobile robots and automated guided vehicles. Sustained 4–24 hr operation cycles, high daily charge cycle counts (1–3 cycles/day), opportunity-charging compatibility.
Power systems for military-derived and commercial UGVs. Ruggedized enclosures with MIL-spec connectors, high-shock tolerance, and wide temperature operation (-20°C to +55°C).
Compact, low-weight battery packs for quadruped and humanoid research platforms. High burst discharge for rapid leg actuation, CAN bus telemetry for runtime state monitoring.
Battery systems for robotic arms on mobile bases. Combines traction battery load with high-peak manipulation loads; EVolve can design for dual-load profiles within a single pack architecture.
Long-endurance battery packs for pipeline inspection robots, industrial inspection crawlers, and survey platforms where runtime maximization is the primary constraint.
Wearable battery packs for exoskeleton and powered orthotic applications. Low weight, body-conforming packaging, and safe discharge chemistry required; discuss geometry constraints in RFQ.
Robotics voltage requirements are driven by motor controller input specifications. Most robotics and AGV motor controllers accept 24V, 36V, 48V, or 72V bus voltages. Higher-voltage platforms (e.g., larger UGVs and mobile manipulation systems) operate at 96V–200V. EVolve MonoLith systems configure to any of these voltages through series cell count selection.
| Platform Type | Nominal Voltage | Typical Capacity | Notes |
|---|---|---|---|
| Small AMR / research robot | 24V – 48V | 1 – 5 kWh | Weight-critical; max energy density priority |
| Mid-size AGV / UGV | 48V – 96V | 5 – 20 kWh | 4–8 hr operation; single or dual shift |
| Large UGV / mobile manipulator | 96V – 200V | 15 – 60 kWh | High peak draw for manipulation joints |
| Exoskeleton / wearable | 24V – 48V | 0.5 – 2 kWh | Geometry-constrained; discuss shape in RFQ |
Discharge rate requirements for robotics are often non-obvious. A 48V / 5 kWh AGV traction battery drawing 50A continuous requires 2.4C, which is manageable with standard NMC. A mobile manipulation arm with 200A peak draw at 48V requires 9.6C peak from the same pack, which demands specific cell selection and busbar sizing. Specify peak and continuous current requirements, not just capacity, in your RFQ.
Robotics applications impose tight physical constraints. Battery mass directly reduces payload and endurance; battery volume competes with sensors, actuators, and structure. EVolve addresses this through:
Provide a mechanical envelope drawing (STEP or DXF) and mass budget in your RFQ. EVolve will return a fit-check confirming achievable capacity within the given envelope and estimated pack mass.
Robotics systems require real-time battery state information for safe operation. The custom BMS (standard in MonoLith systems) exposes:
ROS (Robot Operating System) integration is common in research and commercial robotics. EVolve does not ship ROS drivers, but CAN-to-USB adapters (Kvaser, PEAK, or CANable) enable straightforward CAN bus integration with ROS can_msgs and diagnostic_msgs packages. Customer-side ROS driver development is documented in the BMS ICD.
Robotics programs often progress from single prototype units through small pre-production batches to larger production runs as platforms scale. EVolve supports this ramp:
Full engineering support; STEP CAD and ICD provided; first article inspection.
Production fixtures established; build documentation locked; ATP testing per unit.
Volume pricing; dedicated production slots; ongoing quality records.
Lead times for prototype robotics battery packs are typically 6–12 weeks from signed purchase order and completed electrical and mechanical interface definition. Repeat orders run 4–8 weeks once production tooling is established.
Robotics environments range from climate-controlled factory floors to outdoor field deployments. Standard EVolve MonoLith operational specifications:
| Parameter | Standard Spec | Notes |
|---|---|---|
| Operating temp (discharge) | -20°C to +55°C | BMS thermal cutoffs programmable within range |
| Operating temp (charge) | 0°C to +45°C | Low-temp charge lockout standard for cell protection |
| Storage temp | -30°C to +60°C at ~50% SOC | Extended storage protocol per battery management guide |
| Vibration | Per IEC 62619 / program-specific | Field robot applications; specify vibration PSD in RFQ |
| Shock | Program-specific | Drop and impact tests available; specify in RFQ |
| IP rating | Standard: unrated; upgradeable | IP65/IP67 available; specify sealing requirements |
Field robotics applications (outdoor UGVs, inspection robots) should specify operational environment conditions, including dust, moisture, temperature range, and mechanical shock profile, in the RFQ. EVolve will design enclosure protection and mechanical mounting to match the deployment environment.
Provide platform type, voltage bus, capacity target, mass and volume budget, current profile (peak and continuous), communication interface requirements, and deployment environment.
EVolve reviews for in-catalog fit or custom configuration requirements within 2–5 business days. STEP CAD and electrical ICD provided on contract.
6–12 weeks for first-article prototype. Complete documentation package includes CAN DBC, electrical ICD, and integration guide.
